Structure Characteristics and Applications
VSB-50 Solid Lubricating Bearing is produced by strengthening brass that has good physical performance and good capability for casting. What's more, the brass material has pretty good anti-erosion abitity in air, fresh water and sea water. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. The product is widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.

CHARACTERISTICS
with Solid Graphite Lubrication. Various material specifications, standard and special shapes are also available
VSB-50 Solid lubricating bearings
1. May work without any ol for long period
2. Extremely high load capacity, good anti-wear and lower friction
3. Particularly appropriate for low speed and high load
4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed
5. Good chemical resistant and anti-corrosion characteristics
6. Can b€ used in wide range of temperature from -40℃-+300℃
VSB-50 SOLID LUBRICANT SLIDING BEARINGS material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.
